FEED MC'HANISM Fon AUTOMATIC MAGAZINE-GUNS.

Be it known that I, HERMANN LEHMANN, a

.subject of the King of Prussia, German Emp ire, and a 'resident of Magdeburg, Kingdom AIO -. the following description and will e more particularly pointed out in the .appended of Prussia, Empire of Germany, have invented certain new and useful Improvements in Feed Mechanism for Automatic Magazine-Guns, of which the following is a speciication.

. Thisinvention relates to automatic feed mechanisms for guns and it has for an object` to provide an improved manner ol constructing-and of operating the cartridge lifter..

Another object is toim rove the construction of and manner of fee ing from the magazine.

Other and further objects Will a pear in claims. i.

ments; and Figs. 27 and 28 are vertical transverse sectional views of thel gun showing the feeding mechanism in two positions. c

The magazine sections are each adapted to contain a plurality of paralle rows of cartridges and are each `composed' of a bottom 1 and side walls 2, the ends being 7open tofpermit the rpassa Te therethrough of theliftmg mechanism w'iich will be .heeinafter-de= scribed. To support the vrowsdf cartridges,

the magazine sections have extendin from their si e walls ribs or partitions?v 3 an 4. r

Each magazine section has oir one side in@v terlocking-portions in the form of perforated lugs 7 having chamfered faces and a l"ug.8;:

and on the other side-interlocking portions and is movable axially insaid lugs ,'being `7o in the form of lugs 5 which carry a coupling pin 6 which is held againstv turning -thereim pressed in locking direction by ya springt;A In

operation the interlocking.portions 5 of another magazine section-and the chamfered faces on the coupling pin ,6 andthelugs cause the pinto automatically'interlock said parts by moving axially and then snapping` into the perforations of the lugs yunderthe action of its spring, the interlocking portions:

andthe pin 6 then forming a hinged connecf tion between the sections. The .lug prevents the magazine sections s eparatin ywhen they are outside ofthe magazine gui e 9 as shown in Fig. 28.

The magazlne sections are lfedin a manner to be hereinafter described thro'iigh 'the `mag azine guide 9 and in a direction transverse to` the longitudinal axis of thebarrel'of theignns.

Depending from the top ofthe magazine guide Qis a guide. piece 19 (seeFi'gs. 45 to 9) of such a size as to -pass through the magazine sections., Uponthis guideA p1ece'19, a guide piece 18 (see Figs. 10 to 12) is movablelro'li-r zontally or in directions parallelto thezlinerof. feed of the magazine sections.` .Movable .x'rerf ticallyA or 'transversely of the line-of feed-.onf the .guide pieceVlS is the cartridge lifter .-1'1` (s'ee Figs. 13 to 15) havinganumber of pairs of fingers 12'corres ending; to the num-berief.;

`cartridges in ea'ch ullrowin the magazineer vand o eratingin a manner vto bchereinafter. 1

deswcri ed, to singly feed the cartridgesfrom-t successive rows.

The horizontal movementspr movements in directions parallel .to the fe'd of the maga-f5,l

z ne of theguide piece 18 and consequently.

' -ivard-movenient the cartridge lifter movesfin' the movement of the cartridge `lifterin two directions transverse of the longitudinal axis of the barrel, is produced by the following means. The gun. is provided with a part movable upon the firing of the gun, this part boing in the form of a slide having its for- -ward movement )reduced by a spring 20..

This slide 21 (see i`igs. 23 to 28) is provided with a specially formed cove l22 in the bottom thereof and in whic travels a roller 24 on the end of a 'crank shaft 23.*ivhicli is jour# naledon .the` frame of the gun. .Upon the other extremity of the crank shaft is `a lever i --25 having a slot in which works the pin`26 on guide piece y1.8. During` the movementof theslide, rearwardly, the cartridge"liilil'ier` 'moves in o'iiedi'rection and duiing'its-for the opporsi te direction. l`o :move the care tridge ifter vertically or in two 'other directions i transverse of` lthe longitudinal axis of' the' barrel, the cartridge lifter has connected thereto a rod 15, the.connection` being in the forni-ol a foot 16 on the rod and a groove 1,7 onthe lifter to permit the Alifter to move rela- "tively to the rod in the twodirections iir'st mentioned. This rod carries a roller 28 which is directed upwardly into a groove 27 succession between the cartridges of the near est row and separate the "cartridges to such ari-extent that if the cartridge shells are formed with a rim, lthe introduction oi the uppermost cartridge into thc barrel will 'not be olistruetedby the rim oi"` the next lower above owing to their gradually decreasing in cartridge. Y

tween the4 lower two` cartridges of` a eoln-4 lhe pair of iingers'entering beplete row, enter `first, liftinr` all cartridges above the loweiyoncn and it Vien the "fingers length, enter su ccessivelybetween successive cartridges, each time lifting; all cartridges located above the entering Engler until Vall i cartridges become ,separatedl would thereby lf,injuredl4 spacedby `the fingersy l2.

` f the lingers were not o f different lengths or if they were eqluidistant from the cartridges, they would al 'start `to Venter between the cartridges simultaneously and the upper cartridges I provideV means for maintaiiiihp the cartridgcin spaced relation afterthey lave been This means is movable to permit the cartridges to. be fed i andQtb-'gfliold them. in their fed position'.

springpressed dogs on the guide piece 19 yielding on pressure in one direction by the cartridges. In Fig. 7 it com rises an undie lator spring which also' iel supon pressure by tie cartridges. An in Fi 8, it com prises a plurality of connected fingers which are moved automatically into engarei'nent with the cartridges as the spacing' an lifting fingers 12move out of engagement therewith enr vice versa.

f After the last cartridge of `a row is located on, the to pair of fingers, the pawls 13 on the secon( pair of fingers ressed Vu wardly bysprings and ,pressed ownward y by a cartridge, are able to swing upwardly. Consequently when the cartridp lifter elevates the last eartridgeof a-row, t e pawls 13 pass ybehind a pair of 4.projections 14 (see Fig. l)

onthe partitions 3 and 4 of the magazine sections and when the lifter moves in the direction o movement of the magazine sections,"

said sections are drawn with it, thereby pos-'.7

.tioning the next row of cartridges so that they may be singly fedto the barrel.

To-prevent the magazine sections moving in the direction opposite to the direction of feed, the magazine sections are provided with a plurality of notches 30 in which en.- gage apvoted lever 10. 1

he operation will be apparent from the foregoing description but may be generalized as follows: The slide 21V operates on the cartridge` lifter after the breech has been o cned. .The litter 11 isfirst moved toward t e cartridges in a direction transverse of the same to enter between the cartridges, by means of the roller 24 on crank 23, traveling in 4groove 22 duringthe rearward movement At `the end "off the rearward movement, the roller 28 controlling the verti Acal movement of the lifter is in the osition shown in Fig. 24, 'having passedl Jcncath. switch 29 in the manner shownin Fi 255, so that at the he inning of the forwarr movement of the sli e, thecartrid ge lifter is ino ved to elevate the uppermost cartridge into a po `sition to permit the breech blockv to feed the saine into the barrel on its forward movement. During the forward movement ol the slide, `the lifter is moved away from the caitrid es by means of shait` 23, the can tridges eing supported in the manner before described, and, at the end. of the `forward movementythe cartridge lifter descends to a position where it can be again moved toward the cartridges. The rows of cartridges are successively fedto a )osition Where they may be singly fedi to the arrel.

` `By rounding off the rear'end ofthe groove means of the switch 29, the lifter is caused. to take a path which is curved-cit one portion and .chanifered at another. -It is obvious that the lifter would also be ablev to effect its displacements if its path were rounded ofi or chamfered `at all four angles, the grooves be 1 27 and its forward end being inclined by j ing suitably formed or disposed, or, by inany, direction .inA addition to that illustrated.
